Step-by-step explanation:
it looking for the y in the (x,y) x is domain and y is range
Answer:
system of equations are


Step-by-step explanation:
Let x = number of children's books sold,
and let y = the number of adult books sold
The library sells 376 books at its annual used-book sale
so, we get equation as

Children's books cost $4
So, total cost of children book is 4x
adult books cost $7
So, total cost of adult book is 7y
so, we get total cost is 4x+7y
he sale takes in a total of $2119
so, we get equation as

so,
system of equations are


Answer:
I do not understand she question do you mean the sum of their income is 2640
if so, then the answer is 440 to be x income
Step-by-step explanation:
x income = 20% or 1/5 of y income
y income = 5 of x income
we know that the sum of their income = 2640
which means that
x + y = 2640 =
1/5y + y = 2640
6y/5 = 2640
cross multiply to give us
6y = 5(2640)
6y = 13200
divide through by 6 to give us,
6y/6 = 13200/6
y = 2200
since we know that x income is 20% y income,
therefore, x income =
20/100 * 2200
= 440
therefore,
x income = 440
y income = 2200
